Definitions
- the present invention relates to a method for producing a cage for a ball constant velocity joint and a cage for a ball constant velocity joint itself.
- a cage described here is used in Kugelretereteverschie- hinged joints.
- Continuous ball-sliding joints are used in particular for passenger cars in the area of side shafts or in longitudinal shaft arrangements.
- the longitudinal shafts serve to transmit the driving force from a gearbox to an axle.
- the transmission is arranged in the front region of a motor vehicle, and the longitudinal shaft arrangement serves to transmit the drive forces from this transmission toward a rear axle.
- the Kugelretemaschinebegelenk must be equally compact and lightweight and on the other hand have a high fatigue strength.
- Kugel Stammauerverschiebegelenke with cage have at least one Gelenkau dry- part with a rotation axis and outer ball tracks and an inner joint part with inner ball tracks.
- Ball tracking sliding joints further include a plurality of torque transmitting balls, each guided in associated outer and inner ball tracks, and the cage, the is provided with a plurality of cage windows, each receiving one or more of the balls.
- the torque-transmitting balls are held in particular by the ball cage in a synchronized plane and guided by corresponding pairs of outer and inner ball tracks.
- the ball tracks extend in the mounting area and operating area along the axis of rotation of the joint and have a constant distance (in a radial direction) to the axis of rotation.
- one or two balls are arranged in each cage window.
- the cage moves with the balls along the rotational axis of the outer joint part in the axial direction.
- At least some of the outer and / or inner ball tracks run inclined or at a track taper angle with respect to the central axis. That is, the balls move along the ball tracks not only in the axial direction but also in the circumferential direction.
- kidney-shaped cage windows in the cage are subjected to a calibration process.
- a calibration mandrel is arranged in the cage window and subsequently the complete cage is compressed by a compressive force acting in the axial direction.
- This compression of the cage causes a material flow in the cage, through which a ball guide surface in the cage window is enlarged radially inwards.
- the material of the cage is displaced in the region of the, in the axial directions facing sides of the cage, ball guide surfaces in the radial direction inwards.
- a method for producing a cage is to be provided by which a structurally definable deformation of the cage in the area of the ball guide surfaces is possible.
- the performance of the Kugel GmbHverschiebegelenk in operation should be guaranteed.
- the service life of the ball tracking sliding joint should be increased.
- a cage is to be proposed, which was produced in particular by the method, wherein a suitably shaped cage guide surface is realized. This is achieved with a method according to the features of claim 1 and with a cage according to the features of claim 6.
- a method for producing a cage for a ball-and-cage joint wherein the cage is annular and has cage windows spaced along a circumferential direction for guiding balls of the ball-and-cage joint.

- the cage (in step a)) has an (at least partially or predominantly) spherically shaped inner peripheral surface. In at least one lateral edge region, the inner peripheral surface may be conically shaped.
- step b) in particular (exclusively) in the first region of a (preferably all) ball guide surface (s), a radially outer circumferential surface of the cage is subjected to a compressive force.

- the pressure force acts in particular in the radial direction on the outer peripheral surface. In particular, it additionally acts in the axial direction on the outer peripheral surface. In particular, there is no (or much less) compressive force on the end faces of the cage.
